Hi there,

I have an issue with integrating a dynamic RadMenu in a RadPanelBar.
I am able to create the RadMenu (see Menu.png)

If I integrate the same code in the RadPanelBar the dynamic menu pops up but hovering over the individual menu items don't show the menu items added by the ItemTemplate. 

Anybody any idea?

Regards,

Marcel

Hi Jacques,

You will need to handle the overflow behavior of the menu slider manually like demonstrated in this live demo:
http://demos.telerik.com/aspnet-ajax/panelbar/examples/applicationscenarios/panelbarandmenu/defaultcs.aspx

For example:
body .RadPanelBar,
body .RadPanelBar .rpSlide,
body .RadPanelBar .rpGroup,
body .RadPanelBar .rpItem,
body .RadPanelBar .rpTemplate {
    overflow: visible !important;
}
